DJI Mic 2 range: how far can the transmitter be?

DJI Mic 2 has a maximum range of 250 m (about 820 ft) under FCC rules in the US, or 160 m in CE regions, measured outdoors with a clear line of sight and no interference. In real shoots, with people, walls and Wi-Fi around, plan on much less and keep the receiver in sight of the transmitter. Each transmitter can also record a backup internally, so a dropout doesn't have to ruin a take.

DJI wireless mic range — DJI's maximum ranges, measured outdoors with no obstructions or interference. Bodies, walls and crowded Wi-Fi cut real range sharply.

The official numbers

System	Max range	Conditions
DJI Mic 2	250 m (FCC), 160 m (CE)	Open outdoors, unobstructed, no interference
DJI Mic Mini	400 m	Open, unobstructed, no interference (reference only)

Both systems use the 2.4 GHz band, the same band as Wi-Fi and Bluetooth. There's no distance limit setting; range is set by the radio and the environment.

What cuts the range

Your body. The human body absorbs 2.4 GHz signals well. A transmitter on the chest with the receiver behind the speaker can drop out at a few meters. Keep the transmitter facing the camera side.
Walls, cars and crowds. Each obstacle eats into range. A packed room behaves very differently from an empty one.
Wi-Fi and other 2.4 GHz devices. Conventions, offices and stadiums are crowded with signals.
Metal and pockets. Don't bury the transmitter in a pocket or under a metal badge.
Low battery on either end.

How to avoid dropouts

Keep line of sight between transmitter and receiver whenever you can. Mount the receiver on top of the camera, not behind it.
Clip the transmitter on the outside of clothing, facing the camera, near the collar.
Turn on internal recording on the transmitters as a backup. If the link drops, the transmitter still records 24-bit or 32-bit float WAV on its own 8 GB. See Mic 2 internal recording.
Watch the signal bars on the receiver screen. It shows the signal strength for each transmitter.
Use a wired lav under clothing and keep the transmitter itself in the open. See Mic 2 accessories.
Move closer for interviews. Within a few meters with clear sight, dropouts are rare.

Bluetooth range is different

When a Mic 2 transmitter connects directly to a phone or an Osmo camera over Bluetooth, it isn't using the 250 m receiver link. Expect shorter range and keep the phone or camera nearby. See DJI Mic 2 Bluetooth.

Mic 2 or Mic Mini for distance?

The Mic Mini's quoted maximum is longer, at 400 m, but it has no internal recording to fall back on. For long-distance shots where audio has to be safe, such as a presenter walking away from a camera on a long lens, the Mic 2 with backup recording is the safer choice.
